Sprint plans to deploy Massive (multiple input, multiple output) MIMO radios with 128 antenna elements in its 2.5 GHz spectrum to increase capacity to reach 3 Gbps to 6 Gbps per sector on its 4G network, Sprint notes.
When deployed on the network, Massive MIMO can provide all mobile device users with performance improvements, and those with the latest generation of devices with the most antenna elements will see the best performance.
In recent field testing, Massive MIMO Samsung radios, equipped with vertical and horizontal beam-forming technology, reached peak speeds of 330 Mbps per channel using a 20 MHz channel of 2.5 GHz spectrum.
Capacity per channel increased about four times, cell edge performance increased three times, and overall coverage area improved as compared to current radios.
With 60-MHz channels, Sprint believes it will be able to boost capacity up to 6 Gbps per tower sector.
